Factors affecting the speed of EDM (Electrical Discharge Machining) in plastic mold factories
1. Polarity effect: The phenomenon where different polarities (anode and cathode) result in different amounts of material removal is called the polarity effect.
(1) Anode machining: When using short pulses, electron bombardment is greater than ion bombardment, leading to more material removal from the anode; the workpiece is connected as the anode. Short pulses (less than 40 microseconds) provide high surface quality, low efficiency, and are used for fine machining.
(2) Cathode machining: When using long pulses, material removal from the cathode is greater than from the anode; the workpiece needs to be connected as the cathode. Long pulses (greater than 300 microseconds) offer low surface quality, high efficiency, and are used for rough machining.
2. Pulse parameters: The larger the pulse energy, the more heat transferred to the workpiece, and the greater the material removal. The total erosion amount per unit time for the anode (or cathode) is q = qtf = kwft. Measures: Increase the average discharge current, reduce the pulse interval, increase the pulse frequency, and reasonably select working parameters.
3. Pulse width: Increasing the pulse width increases material removal, but if the pulse width is too short, heat is too concentrated, increasing the proportion of metal vaporization. Vaporization consumes energy, reducing material removal. If the pulse width is too long, heat loss through conduction is too high, also reducing material removal.
4. Material thermodynamic constants: Higher melting point, boiling point, specific heat capacity, latent heat of fusion, and latent heat of vaporization result in less material removal and greater machining difficulty. Higher thermal conductivity leads to faster heat conduction loss, reducing material removal.
